boilers and steam generating equipment quality products for the power and steam generation industry

On issues related to hot water boilers and steam generating equipment quality products for the power and steam generation industry circulating water system of a hot water boiler circulating water system shall have the following to prevent the hot water circulation pump suddenly stopped, furnace water vapor and water hammer protection measures: 1 into the circulating pump, there is provided a check valve between the outlet pipe of the bypass pipe, which should be similar to the diameter of the mother tube, and the bypass pipe cross-sectional area of ​​not less than 1/2 of the cross sectional area of ​​the main pipe; check the flow direction of the pump should be consistent with the direction of flow. 2. Set weight of formula inching valve in the inlet pipe section of the circulating pump, drain pipes which overpressure can open the access to the tank or drain. Second, hot water boiler circulating water system is also designed to meet the following requirements: 1 should be mounted on each cut-off valve or valve outlet pipe boiler, boiler feed water, the supply should be located on the water shut-off valve and check valve. 2. The hot water boiler is running in parallel, the control valve to be provided on each boiler inlet, so that the deviation of parallel boiler water temperature does not exceed 10 ℃. 3. The portion of the high boiler outlet pipe should be installed and easy accumulation of gas and an exhaust gas collection means, not less than an exhaust valve DN20.4. Low system and the lower recesses, should be arranged drain valve and drain pipes . The hot water system should be water pipe back to facilitate the installation position Qingtao decontamination, before and after the decontamination and closing the valve should the pressure gauge, and a small charge of 1 to 2 ratio of the bypass pipe. 6. The boiler should be provided with a plurality of trap and sump for hotspots, catchment trap and drain valve shall be arranged, thermometers, pressure gauges.

After the project identification, party fast technical staff soon made contact with our company, to our installation, commissioning, to ensure the look normal, stable use during boilers and steam generating equipment quality products for the power and steam generation industry operation. Thanks fast boiler professional technical support and good service, I provide a lot of help for the textile dyeing and finishing production company. --customer feedback

What structure and principles of industrial boilers and steam generating equipment quality products for the power and steam generation industrys in particular? What structure and principles of industrial boilers in particular? Industrial boilers has become the hottest on the market boiler boiler. Whether it is gas or gas hot water boiler steam boilers, gas boilers generally use natural gas, liquefied petroleum gas and city gas as a fuel gas fuel. First, the working principle of gas steam boiler: the furnace and the combustion heat of the fuel gas steam boiler, heating pot of water evaporated into steam. Water pan (drum) in the furnace gases are fuel combustion energy released continuously heated, increasing the temperature and pressure steam is generated. When the boiling point of water increases with increased pressure, is sealed pot, the pot water vapor expansion is limited, and therefore the thermodynamic pressure (strictly speaking, water steam boiler). It is widely used as an energy source in the drum, the water is heated and vaporized again to saturation. Second, gas steam boiler basic structure: gas steam boilers and boiler drum consists of two body parts protection, instrumentation equipment, automatic control and protection system of continuous safe operation of its composition. This boiler water wall boiler drum boiler drum in the zoning arrangement, the first two return pipe fireworks smog chamber back to the drum. Connected between the drum and the tank, with water-cooling pipe and the downcomer, which constitute the framework of the combustion chamber. The pot is provided at the top with a steam water separator, to reduce the amount of water extracted from the steam. The bottom of the pan heating surface of the drum, and fireworks waterwall tubes.

Fast boilers and steam generating equipment quality products for the power and steam generation industry summarize the following three methods effective industrial cleaning gas boiler, as follows:

1, the mechanical descaling method
